T o all whomy t may concern Be it known that I, ALBERT BALL, a citizen of the United States, residing at Claremont, in the county of Sullivan and State of New Hampshire, have invented an Improvement in Electric Channel.ing-l\[achines, of which the following description, in connection With the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention relates to pulsators, and particularly to reciprocating pulsators, being heroin shown as applied to tool actuating motors and associate] with improvements in channeling or other stone working machines.

In order that the principles of my invention may be made fully apparent, I have disclosed one type of embodiment. thereof in the accon'lpanying drawings, wherein.

Figure 1 is an end View of a channeling machine embodying one form of my invention, the workingcylinder or motor and portions of the driving connections for the pulsatior being shown in section;

Fig. 2 is a side elevation of the mechanism shown in Fig. 1, the compressor' and a portion of; the pulsator being shownin ver tical section, and the standard. for the electric motor and other parts being represented in dotted lines as shifted to the opposite end of the machine;

Fig. 3 is a. plan View of the driving motor for the pnlsator and a. portion of the means for raising and lowering the working cylinder;

Fig. 4 is a vertical sectional view of one 'form of compressor and pulsator that may be used in connection with the channeling machine;

Fig. 5 is a vertical centralv section of the Working cylinder; and

Fig. G is plan view partly in horizontal. section of a valve employed in connection with the Working cylinder to control the ap plication of'pressure to the piston thereof.

Having reference to that single type or embodiment of the invention herein represented, and referring more particularly to Figs. 1 and 2, the body or frame of the ma chine to which the invention may be applied, and which is herein shown as a channeling machine, is represented at 1, it preferably having r suitable wheels 2 running upon tracks 3. While power may be applied in suitable manner to the Wheels 2, in the present embodiment of the invention I have chosen to employ a separate motor for the purpose represented at 4, which may be an. electric or other desired motor of suitable type. Herein thedriven shaft thereof has thereon abeveled gear 5 meshing (Fig.A 2) With beveled gears 6 and 7 mounted upon a Worm shaft 8, a clutch 9 being mounted upon said shaft and suitably actuated, as by a handlever 10,. whereby either of the gears may be connected with the shaft and the machinev may be driven in either direction or the gears may be disconnected from. the4 shaft and the machine held stationary. Upon the Worm shaft 8 are suitably mounted, preferably at the opposite ends thereof, worms 11 and12 meshing With Worm wheels l13 and 14 upon both axles of the machine.

By the.y employment of a separate track feed motor it is possible not only to use small motors upon the machinc'by dividing the power required for the various operations but a constant as Well independent track movement maybe obtained at all times when the machine is working.

The operating parts of the machine may be disposed in any desired manner. but preferably there is provided an upright standard 15 mounted for adjustment longitudinally of the machine and for a tilting adiustment to the front or rear upon a preferably horizontally disposed trunnion shaft 16, suitably mounted upon the frame of the machine and preferably extending from end to end thereof. As indicated in Figs. 1 and 2. a clamp box 17 secures the standard to the trunnion shaft and permits movement of the standard longitudinally of said shaft or circnmferentially thereof. 'A side brace 18 is preferably employed to aid in supporting the standard, it being represented in Fig. 2

is diagonally disposed and connected at its upper end to the standard and at its lower end bolted to .a sliding clamp box 19;-embracing the 'truiini'on :shaft 16 Land-lpre"ferably made in tufo parts united as shown-bymaw vof .thestandarfl,andinoved to-turnthe llever lowerbolt 20 and -a-n Vupper bolt 21, whichA also secures thel side brace to the 'box. '-"xs will be apparent, the clamp box may be moved laterally1 when it is desired to shift the standard, and it angfextreme. .lateral movement of the standard'is desired, as to the d tted line position 1(indicated-fin-fEig., +2, -1

the sliding 'clamp box maybe removed and "Referringto Fig. il; the cross head iils suitably mounted fas indicated at 22,* Iand hasatf taohed'tliereto preferablya-series or gang'fof tools 23.

'For this purpose the'lowe'r portion of the motor 55 may be adjustably connected to the bearing for thecranlcshat't' 52 and the casing thereof may/,asindieated in Figs. l and 21, be adjustably connected by bolts 55 or otherwise Vto thev lower portion of the pulsator whereby, viewingFig. 2, the said motor 55 may be thrown either to the right or lett, in order that it may b'e kept within the line ot' the standard 15, and hence out of the 'wayl of the 'wall rock whether the standard be mounted at the right hand or left hand end of the machine, viewing llig. 2. Thus the machine can work close up to the wall rock, the motor 55 being adjusted inwardly from said rock in either position of the standard. The sprocket gearing 33 previously referred to as employed to actuate the screw shaft ZS is herein represented. as driven from the crank shaft 52, although it. is apparent it may be actuated from any suitable source. The pulsator 40 suitably connected to the working cylinder 26 in any desired Ainanner and herein (dotted linesFig. 1) ar'e represented, 'for the purpose,-le`xible or jointed metallic, rubber or other suitable connections 56 and 57. While these connections Arepresentthe upper and lower portions of thepulsator as connected with the correspending4 portions Vof the working cylinder, it is apparent that such arrangement may be reversed if desired.

Referring now more particularly te Figs. 4, 5 and' 6, preferably upon the upper end of the pulsator l0 and axially alined therewith is' secured what is herein. designated as a compressor 58. Within the cylinder' of the compressor is mounted for' rooiprocation a piston 59 having a piston rod 60 extending through a stiniing box 61 in the head plate ofthe pulsatorand connected tof'the piston 48" thereof, thecross-'sectionalA area of the cylinder of the compressor herein being the same as--the cross-sectional area of the trunk piston rod-491, so'that herein the effective 'areay of the "upperlface of the piston. 48 is equaled byl the eit'ectiv-e'area of the lower facelthereoi plus the lower effective area of the iston59^`of the compressor, thereby producing'balancedreflective upper and lower pressure areasjifor the'pulsator piston.

Any suitable Huid frn'ay be employed in the pulsa'tor.'but*preferably compressed air is utilized, 'supp` in l any@ suitable manner and' lherein preferably bfy means of` the lcompressoir whereby a'pressure 4may be built up, andhereinjin` both Penti-s of 'the pulsator. Ferthait purposegl have herein represented pressure from the system, all 0fthe cam able valve locking means, herein relnesented as cam levers 67 and 68 respectively, whereby the valves may he locked open when de sired.

ln' the present type of the invention., the lower portion of the compressor cylinder connected by a. vertical passage 69 with the lower portion oi? the cylinder oi? thepulsa tor, such passage being controlled by a valve 70, preferably spring pressed to its seat and provided with suitable moans, :is the rain lever 7l, to lock the same in raised position. Preferably also the upper portion ot the Compressor cylinder is honneeted by a. passage dotted lines Fig. it) 72 with the upper portion of the cylinder of the pulsattn, such ,passage being preferably fontrolli-,wl by a valve 73, herein represented as spring pressed to its seat and having a cam lever `or other device 74C, whereby lthe valve may be locked open. It is apparent that any suitable passages may be provided connecting desired portions of the compressor and pulsator whereby pressure may be built up, preferably at both ends of such pulsator. ,By the described passages and valves controlling the same herein represented for the purpose, when the building up of the air or other fluid in the pulsator is required, the cam levers are thrown off from all the valve stems and the valves are worked according to the travel of the airv into and out of the air compressor. Preferablv a safety valve 75 is provided normally spring pressed to its seat and having itt desired a cam leverv or other device 76 whereby it may be locked open if desired. When the building up of the pressure is finished, or when such pressure begins to issue `from ythel safety valve .7 5, the operator moves thecam levers 67 and 71 into the positions shown in Fig. 4, thereby locking open the valves 65 and 70. rll-his stops tie building up of the pressure in the pulsator as the inlet. air from the upper end of the compressor will then work back and forthl through the inlet passage 62 passing the valve 63. In the action of thel pulsator the' bottoni stroke. of the compressor will work with the bottom stroke of the pulsator,

thusl transforming the compressor into a pulsator and balancing the area of thetrunk i portion of the pnlsator as previously described. In order to permit the eseape=of levers for the different valves are brought into operative engagement with the valves, thus permitting the air or other {iuidfto pass out of the pulsator and out of the compressor. The connections 56 and 57 from the pulsator fl() are represented (Fig. 5) as connected to the 'working cylinder at 7 7 and .7 8 respectively, the upper portion of the Working cylinder having passages 7%), 79 communicating with the connection 56 and the upper portion of said cylinder, whereby pressure may be admitted thereto.

By means of the passage 79 not only'may pressure be admitted to the Working cylinder to give the doWn or Working stroke to the drills but a cushioning action may be afforded to prevent the piston 24 from striking the top head of the cylinder 26 in making its upward stroke. As shown in Fig. 5, Within the Wall of the working cylinder is a vertically disposed passage 80 communicating at its lower end with the lower portion of the Working cylinder and at its upper portion with the passage 79 when a suitably mounted valve 81 (Figs. 5 and G) is actuated for the purpose. While any suitable form of valve or valves -m ay be employed and 'located as desired to control vthe pressure supplied 'to the opposite portions of the Work.- ing cylinder, -I have herein indicated 'for the purpose a rotatably mounted valve having a passage 82 adapted to place-a connection, as 56, from the pulsator in communication with the upper portion of the 'Worki-ngcylinder or, When suitably actuated, in eo-mmunication With the lower -portion thereof, a suitable vent 83 (dotted lines Fig. being provided and communicating with an axial vent84 (Fig. 6) in said valve. whereby pressure in the upper portion of-said cylinder maybe discharged.

[t is frequently desirable to raise 'the cross 'head and drills supported thereby Without 'raising the Working cylinder. fIn the present embodiment of the invention, `this -is preferably "done by raising and holding elevategdfthe piston 24 df Athe Working cylinder. While any suitable mechanism may be em- ?ploy'e'd `for the apurpose, lI herein utilize the two-Way valve 81'mounted in the Working cylinder.

At any time, when the pulsatois in operation, 'or when enough :pressure iis inthe pulsator to enable `it to lift the piston '24, such piston may be raised :and held elevated by turning the said two-way valve, so

'thattheport 82 therein registers with the ports '-79 and :80, the vent passagefll in said 'valve'bein'g brought into register 'with the vent passage 83. The piston Q4: therefore -Will beheld elevated untilA the two-Way 'valve 81 isfturned to register with the ports -7 9 and 79', Wherebf pressure is admitted to the 'upper-Siate o said piston. When the :piston 24 thus raised thermachne may be moved Levante alo -the track as the 4drills are thus eleva from the rock. If, for any reason, it becomes 'desirable or necessary quickl 'to elevate the cross head, :as when the `i'ills Work loose therein, the two-Way valve 82 may, in the 4manner described, be operated Without raising the Working cylinder and Without interrupting the action of the pulsator. A

Having thus described one type or embodiment ofy my invention, I, desireit to be understood that although-specific terms are employed they are `used #in a genericl and idescriptive sense andjnot for' purposes of limitation, the scope of the invention 'being set forth in the following'claims.
